GUILD, Reuben Aldridge, author, born in West Dedham, Massachusetts, 4 May, 1822. He was graduated at Brown in 1847, and in 1848 was appointed librarian of the university, which place he has held to the present time (1887). Under his charge the library has increased from 17,000 to 66,000 volumes. In 1878 a fire-proof library building was completed, in accordance with his own wishes and suggestions. The classification of the library, the arrangement of the books, and the card catalogue, have been highly approved. In 1874 he received the honorary degree of LL.D. from Shurtleff college. In 1877 he travelled in England and Scotland, visiting the great libraries of Oxford, Cambridge, London, Edinburgh, and Glasgow. Besides current articles, including many on Freemasonry, he is the author of "Librarian's Manual, a Treatise on Bibliography, with Sketches of Public Libraries" (New York, 1858); "Life, Times, and Correspondence of James Manning, and the Early History of Brown University" (Boston, 1864);" History of Brown University, with Illustrative Documents" (Providence, 1867); "Biographical Introduction to the Writings of Roger Williams" (1866); "Chaplain Smith and the Baptists" (Philadelphia, 1885); and has edited "Rhode Island in the Continental Congress, 1765-1790," by William R. Staples (Providence, 1870); "Literary and Theological Addresses of Alva Woods," with a life (1868); "Letter of John Cotton, and Roger Williams's Reply" (1866); and "Queries of Highest Consideration," by Roger Williams (1867).
